DISCUSSION
TODAY THROUGH SUNDAY...
MOSTLY DRY CONDITIONS EXIST THIS AFTERNOON UNDER SUNNY TO MOSTLY
SUNNY SKIES. LATE THIS EVENING INTO TONIGHT, CLOUD COVER WILL
BEGIN TO INCREASE FROM THE WEST AS OUR NEXT WEATHER SYSTEM
APPROACHES. AHEAD OF THIS WEATHER SYSTEM, A LOW LEVEL JET WILL
BRING BREEZY SOUTH-EASTERLY WINDS (GUST IN THE 20S AND 30S MPH) TO
EASTERN MONTANA TONIGHT. WITH THIS, A FEW SHOWERS AND WEAK
THUNDERSTORMS ARE FORECAST OVER NORTH-EASTERN MONTANA, BUT SOUTH-
EASTERN MONTANA LOOKS TO REMAIN DRY.
TUESDAY, THE COLD FRONT ASSOCIATED WITH OUR NEXT WEATHER SYSTEM
WILL PUSH THROUGH THE AREA MID-DAY. THIS WILL BRING BREEZY
WESTERLY WIND GUSTS IN THE 20S AND 30S MPH TO MUCH OF THE AREA,
WITH A PERIOD OF STRONGER 40 TO 50 MPH WIND GUSTS AHEAD OF THE
FRONT OVER THE HIGHER ELEVATIONS OF THE BEARTOOTH MOUNTAINS. THIS
COLD FRONT WILL ALSO BRING ISOLATED TO SCATTERED AFTERNOON AND
EVENING SHOWERS AND WEAK THUNDERSTORMS TO THE AREA. WITH THIS
ACTIVITY, LIMITED INSTABILITY (100-500 J/KG OF CAPE) WILL LIMIT
THE STRENGTH OF ANY THUNDERSTORM THAT DEVELOPS OVER OUR AREA.
HOWEVER, MUCH BETTER SEVERE WEATHER INGREDIENTS WILL EXIST EAST OF
OUR AREA IN NORTH DAKOTA AND SOUTH DAKOTA, SO IF YOU HAVE TRAVEL
PLANS EAST OF MONTANA TUESDAY, MAKE SURE TO STAY WEATHER AWARE.
WEDNESDAY IS SETTING UP TO BE THE WINDIEST DAY OF THE WEEK AS
INCREASED MID-LEVEL WINDS AND A DECENT SURFACE PRESSURE GRADIENT
SET UP OVER THE AREA. WITH THIS, WEST TO NORTHWESTERLY WIND GUSTS
IN THE 20S TO 40S MPH LOOK TO BE COMMON, STRONGEST OVER THE
FOOTHILLS WEST OF BILLINGS WHERE OCCASIONAL GUSTS INTO THE LOW 50S
MPH ARE POSSIBLE (50 PERCENT CHANCE AROUND BIG TIMBER AND 70
PERCENT CHANCE AROUND HARLOWTON). ALONG WITH THE WIND, ADDITIONAL
SHOWERS AND WEAK THUNDERSTORMS ARE POSSIBLE WEDNESDAY MAINLY NEAR
THE MONTANA AND WYOMING STATE LINE (30 TO 80 PERCENT, GREATEST
OVER THE MOUNTAINS AND LOWEST OVER THE PLAINS OF SOUTH- EASTERN
MONTANA).
THURSDAY, AN ADDITIONAL WAVE OF ENERGY WILL BRING ANOTHER CHANCE
OF PRECIPITATION TO MUCH OF THE AREA, AT LEAST DURING THE MORNING
HOURS (LOW TO MODERATE CHANCE). WHILE CONDITIONS LOOK TO DRY OUT A
BIT FRIDAY, ANOTHER WEATHER SYSTEM LOOKS TO DROP INTO THE REGION
SATURDAY INTO EARLY SUNDAY, BRINGING AN ADDITIONAL CHANCE OF
PRECIPITATION TO THE AREA (LOW TO MODERATE CHANCE).
WITH THE PRECIPITATION TUESDAY INTO THE WEEKEND, COOLER
TEMPERATURES WILL FAVOR SNOW SHOWERS OVER THE HIGHER ELEVATIONS OF
THE MOUNTAINS AT TIMES (GENERALLY ABOVE 8000 FEET). WITH THIS,
SOME IMPACTS TO RECREATION AND TRAVEL IN THE HIGH COUNTRY ARE
POSSIBLE. THIS INCLUDES TRAVEL OVER THE HIGHEST ELEVATIONS OF THE
BEARTOOTH HIGHWAY IN THE BEARTOOTH MOUNTAINS AND HIGHWAY 14
THROUGH THE BIGHORN MOUNTAINS. LA
AVIATION
LIGHT SHOWERS WILL BEGIN MOVING INTO SOUTH CENTRAL MT AFTER 03Z
THIS EVENING, BECOMING MORE WIDESPREAD THROUGH THE DAYTIME
TUESDAY. AROUND A 40% CHANCE FOR THUNDERSTORMS EXISTS AT KLVM LATE
TUESDAY MORNING THROUGH THE AFTERNOON, WITH AROUND A 20-30%
CHANCE FOR KBIL, KSHR, AND KMLS. MOUNTAIN OBSCURATIONS ARE ALSO
EXPECTED BEGINNING AFTER 06Z TONIGHT. BREEZY WEST TO SOUTHWEST
WIND GUSTS 25-35 KTS ARE EXPECTED DURING THE DAY TUESDAY FOR AREAS
WEST OF BILLINGS. TS
